The structure of DNA is widely accepted to exist as a double helix, but different DNA structures also exist. ... which causes it to fold up into a shape called an 'i-motif'.

For example, we now know that a common enzyme called "DNase I" does not degrade switchback DNA as quickly as it degrades conventional B-DNA (the DNA that is generally found in living organisms).

These so-called normal or reverse Hoogsteen interactions allow a third strand to join and form a beautiful triple helical structure: a triplex (figure 2). In the new article published in the ...

Eggs and embryos from people with polycystic ovary syndrome have altered patterns of so-called epigenetic tags, which could ...

Jun 16, 2023: Revolutionary new method can manipulate the shape and packing of DNA (Nanowerk News) A human cell harbors roughly 2 meters of DNA, encompassing the essential genetic information of an ...

Chromosomes have a thinner junction point called a centromere and at their ends are protected by repetitive sequences of DNA called telomeres. In humans, chromosomes remain in separate territories ...

Switchback DNA is made up of structural sections called "half-turns" that resemble normal DNA but are arranged differently. This diagram demonstrates these structural differences, which give ...

Researchers have developed a revolutionary new method, called triplex origami, to manipulate the shape and tight packing of DNA. The new discoveries open up exciting new possibilities in gene therapy, ...
